Explain how pascal’s triangle allows you to compute the coefficient of x2y3 when (x − y)5 is
expanded

-10

Step-by-step explanation:

Pascal’s triangle: It represents the binomial coefficients. If a binomial expression is (a+b)^n, then (n+1)th row of Pascal’s triangle represents the binomial coefficients or that binomial expression.

The given binomial expression is

The elements of 6th row are 1, 5, 10, 10, 5 and 1.

Therefore, the coefficient of x²y³ is -10.

i think the answer is b)
